EPT is a thermal secure insulating materials in the welding-rod coatings EPT and also utilised in caulking compounds, lubricants, greases, dry-powEPTfire extinguishers, as a slim coating on rubber surfaces to conquer tackiness and sticking, In exterior property paints reduces managing and sagging, and increases weatherability. The addition of mica to all types of sealers for porous surfaces (this sort of as wallboard, masonry, and concrete blocks) drastically decreases penetration and improves holdout. The inclusion of mica in street and highway paints enhances wearability, provides excellent adhesion, and reduces flaking and cracking, also utilized to coat wallpaper due to the fact it imparts an attractive silky or pearly luster, utilised predominantly in paint, plastics and rubber.
We supply muscovite, phlogopite, sericite, biotite and mica powder(dry mica powEPTand moist mica powder).
